  • 07 Feb 2019 08:41:24 PST, (34.703, -116.287), depth 1.6km, 12km W of Ludlow, California
  • Aftershocks: so far (07 Feb 2019, 02:33PM PST) there have been 29 aftershocks recorded, the largest M2.7 (smallest M1.0). More may be expected in the next few days, the largest expected is approximately 1 magnitude unit smaller than the mainshock. There is a small chance (about 5%) that a larger quake could occur, with the likelihood decreasing over time.
  • There were 17 events during the 3 days prior to the earthquake (within a 10 km radius), the largest was M3.5 (2019/02/07).
  • Historical seismicity: since our records began in 1932 we’ve had 62 events of M4 or greater within 10km of today’s event, the largest was M7.1 (1999/10/16) and the most recent was M4.1 on 23 Feb 2016.
  • SCEC Community Fault Model fault associations: most likely Hector Mine rupture dipping (91.6%). Alternates: Not associated with a CFM modeled fault (7.9%), Other CFM faults (0.5%).
  • Nearby faults: Unnamed fault east of Pisgah (5.1 km), Lavic Lake fault zone (Lavic Lake fault) (5.8 km), Pisgah-Bullion fault zone, Pisgah section (Pisgah fault) (9.8 km), Lavic Lake fault zone (10.5 km), Ludlow fault (11.1 km) and Pisgah-Bullion fault zone, Bullion section (Bullion fault) (12.9 km).
